Jan 09, 2008· Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases 2. The efficiency of moving the material forward decreases.

Horsepower is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor.

TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.
